Thanks to everyone for the replies. A fog machine rental is way more then I want to spend just to entertain the neighborhood kids when I don't have any kind of display otherwise. I was considering the dry ice because it's only about $5/lb.
@Toni_Walker @voltronic Same here… as kids my parents entertained us with it out out our reach… the fog and a flashlight in back of it was magical!
@voltronic 👍 The advice you've already been given covers the bases.
I'll just add that when we were kids we played with dry ice once every month for years and never had a mishap. The nearest full-fledged grocery store was 2 hours away, so my parents brought home the perishables with dry ice.

Have fun! And Happy Halloween!
